- Environmental Bioconcentration: An estimated BCF of 12 was calculated in fish for 1,3-dimethylamylamine(SRC), using an estimated log Kow of 2.16(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 200(SRC), determined from a structure estimation method(2), indicates that 1,3-dimethylamylamine is expected to have moderate mobility in soil(SRC). The pKa of 1,3-dimethylamylamine is estimated to be 10.6(SRC) based on analogy to similar amines(3), indicating that this compound will exist primarily in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of 1,3-dimethylamylamine from moist soil surfaces may occur(SRC) given an estimated Henry's Law constant of 4.2X10-5 atm-cu m/mole(SRC), using a fragment constant estimation method(2). 1,3-Dimethylamylamine is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 8.9 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). Environmental biodegradation data specific to 1,3-dimethylamylamine were not available(SRC, 2014). However, similar aliphatic amines (such as amylamine and sec-butylamine) have been classified as readily biodegradable using the Japanese MITI test where these aliphatic am Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 200(SRC), determined from a structure estimation method(2), indicates that 1,3-dimethylamylamine may have moderate adsorption to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 4.2X10-5 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 1.1 and 11.1 days, respectively(SRC). According to a classification scheme(4), an estimated BCF of 12(SRC), from an estimated log Kow of 2.16(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low. 1,3-Dimethylamylamine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). Environmental biodegradation data specific to 1,3-dimethylamylamine were not available(SRC, 2014). However, similar aliphatic amines (such as amylamine and sec-butylamine) have been classified as readily biodegradable using the Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1,3-dimethylamylamine, which has an estimated vapor pressure of 8.9 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1,3-dimethylamylamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be about 8 hours(SRC), calculated from its rate constant of 4.9X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(2). 1,3-Dimethylamylamine does not contain chromophores that absorb at wavelengths >290 nm(3) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

- Uses: DMAA (1,3-dimethylamylamine) is an amphetamine derivative that has been widely used in sports supplements sold in the United States. Also known as methylhexanamine or geranium extract, DMAA is often touted as a "natural" stimulant, with many claimed functional uses including a body-building aid, an athletic performance enhancer, and a weight-loss aid. Although DMAA at one time was approved as a drug for nasal decongestion, no medical use of DMAA is recognized today. FDA is not aware of any reliable science indicating that DMAA exists naturally in plants. Source: Hazardous Substances Data Bank (HSDB)
